• indicates required question

what is the primary purpose of meiosis in the life cycle of organisms that reproduce sexually?
to create four haploid gametes (sex cells) for reproduction
to produce genetically identical cells for growth
to repair damaged tissues and replace old cells
to increase the overall number of chromosomes in the organism
a human body cell is * 1 point
diploid (2n=46

Explanation:

Meiosis is a type of cell division that occurs in sexually - reproducing organisms. It has two rounds of division (meiosis I and meiosis II). The starting cell is diploid (has two sets of chromosomes). Through meiosis, it results in four non - identical haploid cells (gametes). These gametes are used in sexual reproduction.

• The option "To produce genetically identical cells for growth" is incorrect because mitosis (not meiosis) produces genetically identical cells for growth and repair.
• The option "To repair damaged tissues and replace old cells" is also related to mitosis.
• The option "To increase the overall number of chromosomes in the organism" is wrong. Meiosis reduces the chromosome number by half (from diploid to haploid).

Answer:

To create four haploid gametes (sex cells) for reproduction
